Problems solved by technology

The electrical utility meters used to measure electrical consumption by utility companies in commercial and / or residential occupancies present a potential life, safety, fire and explosion hazard.
Generally, electrical meters, as well as appliances, cars and other electronic apparatuses that present a potential fire hazard, only include a circuit breaker or fuse.
Any energized device represents a potential fire / safety hazard.

Embodiment Construction

[0011]Referring to the several views of the drawings, the electronic safety shutoff of the present invention is shown and is generally indicated as 10. Presently utilized electrical utility meters used to measure electrical consumption by utility companies in commercial and / or residential occupancies present a potential life, safety, fire and explosion hazard.

[0012]The electronic safety shutoff 10 provides a double action safety / emergency shutoff / disconnect including a plurality of sensors 12, with dual redundancy to prevent erroneous shut off. If a single sensor 12 should fail, power will remain on (dual redundancy). Conversely, actual over temperature and / or smoke detection will trigger more than one sensor 12 and immediately disconnect the power to prevent further damage, burning, melting etc. This design will kill power if smoke or overheating temperature is sensed, thereby preventing further damage and significantly increasing safety. In a preferred embodiment, one or more of t...

Abstract

Electronic safety shutoff with dual redundancy is provided for use in combination with an electronic device to prevent fire, explosion, electrocution or shock. In one embodiment, four sensors, including two smoke sensors and two temperature sensors provide input to the logic gate circuit. The logic gate circuit determines the output signal to maintain power or interrupt power. Any combination of two or more sensors triggering will activate a power interrupting signal by the logic gate circuit, thereby activating an emergency power shutoff.

Description

BACKGROUND OF THE INVENTION[0001]Field of the Invention[0002]The present invention relates to electrical utility meters and, more particularly, to an electrical utility meter including a logic circuit adapted to shut off in response to at least two sensors being triggered.[0003]Discussion of the Related Art[0004]The electrical utility meters used to measure electrical consumption by utility companies in commercial and / or residential occupancies present a potential life, safety, fire and explosion hazard. Generally, electrical meters, as well as appliances, cars and other electronic apparatuses that present a potential fire hazard, only include a circuit breaker or fuse.[0005]Accordingly, there exists a need for an electronic safety shutoff design in an electrical utility meter for shutting off power if smoke is sensed and / or if a particular temperature is sensed, thereby preventing further damage and increasing safety.[0006]This technology can be used in electrical utility meters as...
